Abstract
Most fruits and vegetables have to be stored in cold and controlled atmospheres. Vegetables and climacteric fruits are very sensitive to the presence of ethylene gas, which acts as a ripening hormone and plays a regulatory role in many plant metabolic processes. Produce and flowers display ethylene receptors at their surface. Their actuation promotes ethylene production by the fruit itself, accelerating its ripening and aging. One way to moderate ethylene production is to slow down the metabolism by keeping the produce in a controlled atmosphere (2% oxygen, 2-5% carbon dioxide, 93-96% nitrogen). In this study, the control of ethylene concentration is performed in ambient air by using a photocatalytic converter, which mineralises ethylene into water and carbon dioxide. This device appears, therefore, as a flexible and inexpensive alternative to the catalytic converter for small producers.
